use laravel jwt authentication only for api without affecting web - laravel

Question

I have an issue with authentication in laravel web, I only what to use the JWT authentication for the api only, I notice whenever I change guard in defaults to web 'guard' => 'web' and I try to login with postman using my api it will not work and this error show("message": "Method Illuminate\Auth\SessionGuard::factory does not exist.") but the web will work, if I change it to 'guard' => 'api' I will not be able to login in the web but the api postman login will work.
Only web will work
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'jwt',
'provider' => 'users',
],
],
Only api will work
'defaults' => [
'guard' => 'api',
'passwords' => 'users',
],
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'jwt',
'provider' => 'users',
],
],
Route
Route::group([
'prefix' => 'auth'
], function () {
Route::post('login', [AuthController::class, 'login']);
Route::post('logout', [AuthController::class, 'logout']);
Route::post('refresh', [AuthController::class, 'refresh']);
Route::post('me', [AuthController::class, 'me']);
});
Controller
class AuthController extends Controller
{
public function __construct()
{
$this->middleware('auth:api', ['except' => ['login']]);
}
public function login(Request $request)
{
$credentials = $request->only('email', 'password');
if ($token = $this->guard()->attempt($credentials)) {
return $this->respondWithToken($token);
}
return response()->json(['error' => 'Unauthorized'], 401);
}
public function me()
{
return response()->json($this->guard()->user());
}
public function logout()
{
$this->guard()->logout();
return response()->json(['message' => 'Successfully logged out']);
}
public function refresh()
{
return $this->respondWithToken($this->guard()->refresh());
}
protected function respondWithToken($token)
{
return response()->json([
'access_token' => $token,
'token_type' => 'bearer',
'expires_in' => $this->guard()->factory()->getTTL() * 60
]);
}
public function guard()
{
return Auth::guard();
}
}
I just want to use JWT authentication for only the api without affecting the web, Thanks

Answer 1

What defaults.guard config does is setting the default guard to be used if none specified.
If you want 2 different authentication methods and guards you should specify each by name in your middlewares.
So instead of Route::middleware('auth')->get(...);
you should write Route::middleware('auth:api')->get(...);
If you want to protect all routes in a group you can do it in app/Http/Kernel.php by adding this lines:
protected $middlewareGroups = [
'web' => [
...
'auth:web'
],
'api' => [
...
'auth:api'
],
];

Answer 2

you can use this
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
and in controller where you need api guard use this
auth('api')
for example in login controller
public function login(Request $request)
{
$validator = Validator::make($request->all(), [
'email' => 'required|email',
'password' => 'required|string|min:6',
]);
if ($validator->fails()) {
return response()->json($validator->errors(), 422);
}
if (!$token = auth('api')->attempt($validator->validated())) {
return response()->json(['error' => 'Unauthorized'], 401);
}
$token = auth('api')->claims(['user' => auth('api')->user()])->attempt($validator->validated());
return $this->createNewToken($token);
}

i use this controller and works for me
class UserController extends Controller
{
public function __construct()
{
$this->middleware('auth:api', ['except' => ['login', 'register']]);
}
/**
* Get a JWT via given credentials.
*
* #return \Illuminate\Http\JsonResponse
*/
public function login(Request $request)
{
$validator = Validator::make($request->all(), [
'email' => 'required|email',
'password' => 'required|string|min:6',
]);
if ($validator->fails()) {
return response()->json($validator->errors(), 422);
}
if (!$token = auth('api')->attempt($validator->validated())) {
return response()->json(['error' => 'Unauthorized'], 401);
}
$token = auth('api')->claims(['user' => auth('api')->user()])->attempt($validator->validated());
return $this->createNewToken($token);
// return response()->json([
// 'token' => $this->createNewToken($token),
// ]);
}
/**
* Register a User.
*
* #return \Illuminate\Http\JsonResponse
*/
public function register(Request $request)
{
$validator = Validator::make($request->all(), [
'name' => 'required|string|between:2,100',
'email' => 'required|string|email|max:100|unique:users',
'password' => 'required|string|confirmed|min:6',
]);
if ($validator->fails()) {
return response()->json($validator->errors()->toJson(), 400);
}
$user = User::create(array_merge(
$validator->validated(),
['password' => bcrypt($request->password)]
));
return response()->json([
'message' => 'User successfully registered',
'user' => $user,
], 201);
}
/**
* Log the user out (Invalidate the token).
*
* #return \Illuminate\Http\JsonResponse
*/
public function logout()
{
Auth::logout();
return response()->json(['message' => 'User successfully signed out']);
}
/**
* Refresh a token.
*
* #return \Illuminate\Http\JsonResponse
*/
public function refresh()
{
return $this->createNewToken(auth::refresh());
}
/**
* Get the authenticated User.
*
* #return \Illuminate\Http\JsonResponse
*/
public function userProfile()
{
return response()->json(auth::user());
}
/**
* Get the token array structure.
*
* #param string $token
*
* #return \Illuminate\Http\JsonResponse
*/
protected function createNewToken($token)
{
return response()->json([
'access_token' => $token,
'token_type' => 'bearer',
'expires_in' => auth('api')->factory()->getTTL() * 60,
'user' => auth('api')->user(),
]);
}
}
and routes
Route::prefix('user')->middleware('api')->group(function () {
Route::post('/login', [UserController::class, 'login']);
Route::post('/logout', [UserController::class, 'logout']);
Route::post('/refresh', [UserController::class, 'refresh']);
Route::get('/user-profile', [UserController::class, 'userProfile']);
Route::post('/register', [UserController::class, 'register']);
});
